“The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.”
― George Bernard Shaw, Man and Superman
I think the most "successful" people are the people I would not hear about. Likely, some mid-level executives, engineers, professionals. They have enough. They don't need to "move up". They're happy. They don't need to tell people about their stories. So we never hear about them.
Well, in that case, we didn't really go extinct. The distinguishing feature of our kind is our rational faculty, allowing for discourse with others to explain our past actions and future intentions, that grows our self-consciousness (self requires an other[1]) and births civil society. Not our genetic makeup. If some insect species develops self-consciousness and civilization, I'd argue that we ought to recognize it as of our kind. Moreso than, say, apes who are closer to "us" genetically.
[1] Hegel. Phenomenology of Spirit, 1807. "self-consciousness achieves its satisfaction only in another self-consciousness… A self-consciousness exists for a self-consciousness. Only so is it in fact self-consciousness, for only in this way does the unity of itself in its otherness becomes explicit for it."
We would still be trying to kill food by throwing rocks if we were wise.
Which is funny, because it would have been those first wise people who took the steps to get here.
